How did the word mom come from?

Parents are traditional names in China. Before the Qing Dynasty, China's scientific research system was mainly in classical Chinese. After the Revolution of 1911, westernization became more and more popular, and people who returned from studying abroad brought names like mom and dad back to China. Slowly, it became popular. "Mom" is the simplest pronunciation, which is the natural result of the baby's mouth opening and exhaling. The second simple pronunciation is "Dad". When the baby's eyes gradually become the focus of seeing things clearly, the contact range of eyes begins to gradually expand, and the process of understanding the environment begins. First of all, the first one is to perceive the source of food and clothing-"mother" (from a global perspective, there are great differences between languages, but the exception is that the pronunciation of "mother" is extremely eye-catching, which is mainly caused by the characteristics of baby pronunciation and the consistency of basic instinctive demand for food and clothing. At this time, the meaning of "mother" is not really "mother", but only a symbol of milk and warmth. With the strengthening of the baby's cognitive ability to the environment, these basic instinctive needs are gradually combined with the specific environment and objects. With the development of vocal organs, one day the baby opened his mouth and inadvertently made the simplest "horse" sound. Generally, the mother who first hears this voice is always the one who undertakes the task of feeding, so the mother will subjectively think that this is the child calling herself, so she will make some surprises, such as taking the initiative to feed, caring and so on. Finally, one day, the baby gradually made another sound besides crying as a means to express his needs. At this time, on the basis of knowing and not knowing, the baby will feel familiar and unfamiliar, adaptive and uncomfortable, and gradually there will be a need for safety. Fear comes when the familiar "mother", which symbolizes food and clothing, is absent. This stage should be from early lactation to middle and late lactation. Dad is a kind of address for father, which is often used in spoken language, and is also called dad, dad, dad and so on. First, the word "dad" exists in about 70% of human languages, with similar meanings, which may be the first word spoken by ancient humans. Anthropologists have been speculating about the original language form of human beings through various methods. A few days ago, French anthropologists said that because the word "dad" exists in about 70% of human languages and has similar meanings, it is probably the earliest word that ancient humans can speak. At present, there are many nouns with similar pronunciations and meanings in more than 6,000 kinds of spoken languages, especially words like "mom" and "dad" which refer to relatives. Some linguists speculate that these words have been used for at least 50,000 years since the formation of ancient human languages. However, because these experts have not determined the frequency of these words in distant language families, they cannot confirm the above assertion. However, according to the latest issue of New Scientist magazine, scientists from the French Federation of Linguistics and Prehistoric Anthropology recently conducted a survey on the word "dad". They found that this word basically exists in 14 major language families. In 7 1% of the languages studied, the word "dad" means father or his male relatives. Scientists in charge of this research believe that there may be only one explanation for the unity of "dad" in various languages: "dad" is the first word that human ancestors can say. In addition, a linguist at the University of Pennsylvania said that because babies are likely to associate the first sound they can pronounce with their parents, the meaning of the word "dad" is basically the same in all languages.
